MasterInject 1320 - Single component polyurethane injection resin for sealing of cracks in concrete

How does MasterInject 1320 work?

MasterInject 1320 is a single component hydrophilic injection resin which forms an impermeable flexible seal when injected into cracks in concrete.

Where is MasterInject 1320 applied?

• Permanent crack sealing of below ground structures such as tunnels, shafts, basements and underpasses.
  
• Stopping of minor water seepage.
  
• Can be injected after MasterInject 1335 in cracks where higher water flows occur.
  
• Single use injection through MasterSeal 909 injection hoses
  

What are the advantages of MasterInject 1320?

• MasterInject 1320 is based on a moisture curing MDI Isocyanate and does not require the addition of a "reactor" to activate the material
  
• The product cures to form a flexible and impermeable seal where further limited movement of the concrete is anticipated
  
• It reacts under wet / damp conditions and foams upon contact with water
  
• Good bonding to damp / wet surfaces
  
• Permanent sealing effect
  
• Low viscosity – allows penetration of fine cracks
  
• Does not contain toxic TDI Isocyanate
  
• Has a low shrinkage compared to standard TDI based injection sealing products
